Victoria Police has launched an online service for reporting harassment on public transport:

To initiate the service, people can text ‘STOPIT’ to 0499 455 455.

Once you text STOPIT you will receive a link to an online form that allows you to:

– share details of the incident, such as the type of behaviour, or when or where it occurred
– upload an image or video (if you choose).

You can complete this form at the time of the incident or after it has occurred.

NOTE: STOPIT is not monitored live. For immediate police assistance, call Triple Zero (000) and speak to an operator.
